Abstract
The invention discloses a vibrating screen with a hydraulic cylinder, which belongs to screening equipment and can be widely used for screening and classifying ores, coals and other non-metal materials. The vibrating screen comprises a screen body, a screen body excitation beam, a pump station system, a base frame, the hydraulic cylinder, a fixed component, a bracket and a damping spring, wherein the screen body is supported on the bracket by the damping spring. The vibrating screen is characterized in that: one end of a hydraulic oil pipe is connected with the pump station system, while the other end is connected with the hydraulic cylinder; and the hydraulic cylinder is fixed on the base frame and is connected with the screen body excitation beam through the fixed component. The hydraulic cylinder can drive a plurality of types of vibration equipment through excitation and can realize stepless speed adjustment to the maximum of 1,000 times per minute, vibration parameters of the hydraulic cylinder are adjustable, are easy to control, and can ensure that a screening machine runs stably without resonances; besides, one pump station system can drive a plurality of hydraulic cylinders to perform excitation, and can increase the exciting force and meet the needs of a heavy-type efficient vibrating screen.

Technical field
The present invention relates to a kind of vibrating screen with hydraulic cylinder, belong to screening plant, can be widely used in the screening and the classification of ore, coal and other nonmetallic materials.
Background technology
Current, known vibratory sieve adopts mechanical eccentric formula inertial excitation mode exciting mostly, and its major advantage is that simple in structure, price is low and make easily, but has following problem: (1) vibration parameters, be that frequency, amplitude and treating capacity are non-adjustable, can not satisfy the multi-state requirement; (2) start and downtime long, covibration is serious, causes the sieve nest damage, has a strong impact on organism life-span; (3) be subjected to the restriction of common electric machine specifications parameter, be difficult to the low frequency high amplitude vibration that realizes that some material is required.
Summary of the invention
The objective of the invention is for overcoming above-mentioned the deficiencies in the prior art part, a kind of vibrating screen with hydraulic cylinder is provided, and it includes vibratory sieve sieve nest and hydraulic exciting part, and hydraulic jack plays the exciting effect, its reciprocating motion drives vibratory sieve sieve nest up-down vibration, supports vibratory sieve work.
The present invention is achieved through the following technical solutions: a kind of vibrating screen with hydraulic cylinder, comprise sieve nest, sieve nest exciting beam, pumping station system, underframe, hydraulic jack, retaining element, support, damping spring, sieve nest is supported on the support by damping spring, it is characterized in that: an end of hydraulic oil pipe is connected with pumping station system, the other end of hydraulic oil pipe is connected with hydraulic jack, hydraulic jack is fixed on the underframe, and hydraulic jack is connected with sieve nest exciting beam by retaining element.
Described sieve nest is a tilting gearing, and its inclination alpha is 10 °～30 °.
Left and right symmetrically is evenly equipped with hydraulic jack below the described sieve nest.
Advantage of the present invention is: this hydraulic jack exciting can drive polytype vibratory equipment, can realize stepless time adjustment, maximum can reach per minute 1,000 times, its vibration parameters is adjustable and easy control, can guarantee that also screen(ing) machine operates steadily, no covibration, and a pumping station system can drive many hydraulic jack excitings, can increase exciting force, satisfy the needs of heavy high-efficiency vibration sieve.
